Concentrations of Heavy Metals and Selenium in Tissues and Some Foods of Walrus ( Odobenus rosmarus rosmarus ) from the Eastern Canadian Arctic and Sub-Arctic, and Associations between Metals, Age, and Gender
Atlantic walrus (Odobenus rosmarus rosmarus) harvested at Igloolik and Hall Beach (Foxe Basin) and Inukjuak and Akulivik (eastern coast of Hudson Bay) and clams (Mya truncata) and cockles (Serripes groenlandicus) collected at Igloolik were analyzed for heavy metals and Se. Pb was high in walrus from...
